Although I have described the Venetian blind as being operatable in twosections, it is obvious that three or more sections can be similarlyoperated, it being only necessary to duplicate the mechanism foroperating one of said sections.

Referring more particularly to Figure 7, there is shown a modified formof the invention in which a rear slot 30 is provided in the slat Ila,which slot 30 is open at one end thereof. A 010- sure means, generallyindicated as 3| is secured to the edge 32 of the slat Ila, and ispivoted thereto by a pin 33. The closure means 3| is provided with acutaway portion am to coincide with the rear slot 30. Insuchaconstruction, the ropes 34 can initially be more easily put intoposition for operation, by swinging the clip 3| open, inserting theropes 34, and closing the clip.

Second to the cord 34 is a clip 35'which engages '.the"underside of theslat Ila to selectively open or close the same, when the Venetian blindis operated.

Referring to Figures 4 and 5 of the drawing, there is'shown a modifiedform of the invention, in which a double tape 36 is employed. The doubletape 36 is otherwise similar to the tape I9, but is provided with anopening 31 in the upper rear portion thereof, and 'a lower opening 38 inthe front portion thereof. The cord 39 enters the aperture 31 and passesbetween the double tape 36 and extends through the aperture 38. Thus,the major portion of the cord 39 is concealed from view, and generallythe Venetian blind has a more attractive appearance. 7

Otherwise, the operation of the modified form ofthe invention'shown inFigures 4 and 5 is identical to the operation of the invention shown inFigure 1. 7

It should be borne in mind that the present invention generally embracesthe feature of pro- ?viding a slat for a Venetian blind having twospaced apart pairs of slots, each of which com- ,prises front and rearslotted portions, preferably in substantial horizontal alignment. Theinvention also, embraces a Venetian blind adapt- .ed to be operated insection wherein pulling' means cooperate with a plurality. of slats toselectively move some of said slats while others remain at rest.

In the operation of the Venetian blind, which forms the presentinvention, the slatsll are selectively opened or closed by operation ofthe cord l2. To close a certain ,section of the Venetian blind, inaccordance with the present invention, the slats ll are first moved toopen position as shown in the upper section of the Venetian blind ofFigure 1. With all the slats H in open position, either the'upper orthelower half of the Venetian blind can be se- 1 lective'ly closed byeither pulling the cords 2| or 2lb. It should be pointed out however,that the slats mustbe in the open position before they :are adapted forsectional closing. Also,"'onc e a sectionof the slats has beenclosed,and it is desired to open the same, it isnecessary to close all'sections of the Venetian blind, and then simultaneouslyopen allthe'slats through the operation of cord I 2. After the Venetian blind iscompletely opened, any section thereof may then be selectively closed.

Modified forms of the present invention will --be apparent to thoseskilled in the art and it is i dsired'to be limited'only by the claimsappended hereto.

' thereof,

What I claim is:

1. In a Venetian blind adapted to be operated in sections, a pluralityof slats, some of said slats each being provided with center and rearslotted portions intermediate the ends and center of the slat, alignedtapes at the sides of said slats adjacent the slots, the front tapesbeing provided with an aperture, a pulley carried by the rear tape, anda rope disposed in said rear slotted portions passing over said pulleyand through the aperture in said associated tape, and said rope beingenlarged at spaced apart portions throughout its length, said, enlargedportions engaging the underside of the said rear slotted portions whensaid rope is pulled, whereby said some of said slats tilt while theremainder stay at rest.

2. In a, Venetian blind adapted to be operated in sections, a pluralityof slats, each of which is provided with center and rear slottedportions intermediate the ends and center of the slat, aligned tapes atthe sides of said slats adjacent the" slots, the front tapes beingprovided with an aperture, a pulley carried by the rear tape, and aro'pedisposed in said rear slotted portions oisome of said slats andpassing over said pulley and through the aperture in said associatedtape, and. said rope being enlarged at spaced apart portions throughoutits length so that said enlarged portions engage the underside of thesaid rear slotted portions of some of said slats when said rope ispulled, whereby said some of said slats'tilt while the remainder stay atrest. 3. In a Venetian blind adapted to beoperated in sections, aplurality of slats, some of said slats being provided with center andrear slotted portions,

pulling means cooperating with said'rear slotted portions of said someof said slats to operate the same.

4. In a Venetian blind adapted to be operated in sections, a pluralityof slats, some of said slats being provided with center and rear slottedportions in substantial horizontal alignment, rope and pulley meanscooperating with said rear slotted portions of said some of said slatsto operate the same. i

5. A tape for use in a Venetian blind in combination with a pullingrope, said tape having a front run comprising, a rear portion having anaperture, and a front portion having an aperture spaced from said firstmentioned aperture in said rear portion, whereby said pulling rope mayenter through the aperture in said rear portion'of the tape and passbetween the front and rear portions of the tape to pass through theaperture in the front portion of said tape. 1 Y

6. In a Venetian blind'adapted to'have its slats operated to closedposition in sections, a plurality of slats in each section, tapesassociated with said slats and having front runs and back runs, a pulleymounted upon the back run of each tape, the front run of each tapehaving an aperture therein, and a rope havin one end portion passingthrough the aperture in the front run of each tape and having itsopposite end portion passing over said pulley and bein'g operativelyconnected to each of the slats in one of said sections.

7. In a Venetian blind having upper and lower sections each comprising aplurality of slats, tapes associated with the slats of both sections andhaving front runs and back runs, a pulley mounted upon the back runs ofsaid tapes adjacent the upper end portions thereof, the front runs ofsaid tapes having apertures in the upper end portions ropes having end"portions. passing through the apertures of the front runs of the tapesand being disposed outwardly thereof, the opposite end portions of saidropes being trained over said pulleys and bein operatively connectedwith the slats in the upper section of the Venetian blind, whereby theslats of the upper section may be tilted to closed position by pullingon the outer end of said ropes, pulleys mounted upon the back runs ofsaid tapes intermediate the upper and lower ends thereof, the front runof said tapes having apertures disposed intermediate the upper and lowerends of said tapes, and ropes having end portions thereof passingthrough the intermediate apertures in said tapes and being disposedoutwardly thereof and having their opposite end portions trained oversaid intermediate pulleys, and having operative connections with theslats in the lower section of the Venetian REFERENCES CITED Thefollowing references are of record in thefile of this patent:
